New highly accurate digital temperature sensor from ams helps designers of cold-storage equipment to meet demanding error budget targets
New AS6200C sensor provides easy-to-use digital output and requires no user calibration or linearization
Premstaetten, Austria (6 December, 2017) -- ams (SIX: AMS), a leading worldwide supplier of high-performance sensor solutions, today introduced the AS6200C, a digital temperature sensor IC which offers highly accurate measurements in the temperature range -20°C to +10°C.
The superior performance of the AS6200C makes it easier for designers of refrigerators and data loggers in cold-chain storage equipment to meet demanding targets for system-level accuracy.
The AS6200C’s measurements are accurate to ±0.2°C between -20°C and 10°C, the temperature range over which storage equipment for perishable goods operates. The sensor’s accuracy is guaranteed over the device’s supply voltage range of 1.8V to 3.6V.
In temperature control and temperature logging applications, the total error budget is made up of multiple components. By minimizing the error at the point of measurement, the designer gains extra headroom for other error and noise sources, such as the heat generated by board-mounted com-ponents. The use of the highly accurate AS6200C gives the designer more flexibility to modify other elements of the system design while keeping total error below a specified maximum level.
The AS6200C integrates a sensor front end, 12-bit analog-to-digital converter and digital logic in a small WL-CSP package. It provides a digital output over an I2C interface to any host microcontrol-ler. The device performs on-board digital signal processing, which means that it needs no user cal...
The AS6200C integrates a sensor front end, 12-bit analog-to-digital converter and digital logic in a small WL-CSP package. It provides a digital output over an I2C interface to any host microcontrol-ler. The device performs on-board digital signal processing, which means that it needs no user calibration, and its linearized output requires no compensation by an external microcontroller.
The AS6200C is intended for use in equipment for storing and transporting food, pharmaceuticals, flowers and other perishable goods, as well as in domestic and commercial refrigerators. It is very well suited to data loggers that comply with the EN12830:1999 class 1 standard.
The new device extends the ams family of small, accurate digital temperature sensor ICs, joining the AS6200 sensor, which achieves peak accuracy between 0°C and 65°C.
“The AS6200C offers the market a unique combination of small size – its footprint is only 1.5 mm2 - very high accuracy over the cold-chain monitoring and storage temperature range, and a convenient digital output requiring no calibration or linearization. It provides a new example of the value of the low-noise, high-sensitivity, high-linearity semiconductor technology underlying the outstanding per-formance of ams’ sensor solution products,” said Nikolai Haslebner, Marketing Manager at ams.
The AS6200C is available in production volumes. Unit pricing is €0.60 in order quantities of 1,000 units.
An evaluation board for the AS6200C digital temperature sensor is available from the ams ICdirect online store. For sample requests or more technical information, go to www.ams.com/temperature-sensor/AS6200C.

Sensors Enable the Smart Home
Consumer acceptance and demand for “smart home” capabilities must be driven by the simplicity of use and perceived value those smart home services deliver. Real-time sensing is the critical touch-point behind delivering both simplicity and value, enabling the IoT’s “things” to deliver their service.
New small, low-power MOX VOC sensors: how might they be used for indoor air quality monitoring?
Stories in the news media are heightening people’s awareness of the importance of the quality of the air we breathe. The average human inhales about 15kg of air a day, 80% of it indoors. And while the quality of outdoor air is routinely monitored by public agencies, Indoor Air Quality (IAQ) monitoring is the responsibility of the building’s operator. A new generation of small, surface-mount, low-power VOC (volatile organic compound) gas sensors offering the potential for distributed, local IAQ monitoring by small and affordable devices. This article explains the operation of these new VOC sensors and the differences between them and absolute single-gas sensors. It also shows how they can provide data which enables air management equipment to respond most efficiently and effectively to variations in indoor air quality.
